Banda

Almost right
Almost right The Portuguese were there first, then came the Dutch, then the English took one of the Banda Islands, called Run, the Dutch couldn't dislodge them so burnt all the nutmeg plantations on Run, leaving the British with a worthless piece of land, but despite its uselessness they dug in just to pester the Dutch, so a trade was done, Manhatten for Run. Much later during the Napoleonic Wars, when Holland was occupied by the French the British took all the Dutch colonial possessions, they kept most of them, but gave back Indonesia, after stealing the nutmeg from Banda, and thus Banda lost its worth, although Dutch mismanagement had already caused the VOC to go bankrupt despite their monopoly in the spice trade. As for Manhatten, well the English lost it to you guys... So we all lost in the end, but I would say the original inhabitants of Banda and Manhatten the most, as they were either exterminated or died from disease.
